Thanks to accurate physical models and an optimised implementation, NOVI-SIM allows you to test and adjust CT acquisition parameters. >> read about Novi-Sim models and benchmarking
NOVI-SIM is a valuable tool for training CT operators and engineers.
NOVI-SIM is particularly powerful in generating images to train artificial intelligence learning algorithms.
Robust algorithms based on Novitom’s more than twenty years of experience in tomography.
Simulation of X-ray radiographs in seconds and volume reconstruction in minutes
User-friendly interface and intuitive settings
Numerous adjustable parameters in the acquisition chain and experimentally validated models
Geometry and acquisition parameters as well as the Region of Interest (RoI) within the detector are defined by the user in the left hand side panel while the 3D view of the scene is simultaneously updating.
Real-time updating of the projection (X-ray image) displayed when any acquisition parameter is changed (including source and detector configurations) or when the angle, position or composition of the object is modified.
NOVI-SIM runs on any recent computer (less than 10 years old). User comfort depends on system performance. For tomographic reconstruction, an Nvidia GPU is strongly recommended.

Novi-Sim is an X-ray radiography and tomography simulation software that models the complete image acquisition chain, including the X-ray source, filters, sample, scintillator, sensor, optics and camera. It generates virtual radiographs and a reconstruction module is included to compute tomographic volumes.
Novi-Sim can simulate X-ray projections, i.e. radiographs, from any angle and supports circular and helical tomography scanning trajectories. It includes accurate physical models for absorption, phase shift and scattered radiation, along with tunable X-ray source and detector parameters.
Novi-Sim simulates X-ray tubes (reflection and transmission) and monochromatic sources. User-defined spectrum can also be uploaded in Novi-Sim, especially for CT configuration using LINAC. Synchrotron radiation sources are also available in option.
Yes. Novi-Sim can model complex samples containing multiple materials and simulate defects such as holes, inserts and cracks. Mesh objects can be imported in STL format.
Yes. The software can simulate a wide variety of scintillators sensors and cameras. Detection systems can be configured with the relevant parameters, including direct coupling for flat-panel detectors or coupling through an optical lens.
Yes. Novi-Sim can help optimise image quality and acquisition times by varying parameters such as X-ray current and voltage, source-detector distance, number of projections, exposure time, and local or global tomography configurations.
The first time you configure a given complete set-up, and depending on object complexity, it may require between 5 to 15 minutes, assuming you’ve collected all relevant information for the source, detector and object.
The modification of a given parameter results in a simultaneous update of the current displayed projection.
Computation time of projections depends on the number of useful pixels on the detector (that you can determine) and the number of cells (triangle) in the object. Typically projections are computed within a few minutes and reconstruction in less than a minute.
